"Derrik removed a fair amount of sand box sand that i was having a hard time disposing of, then dug out 5 cement footing to our old playground and finally leveled and landscaped a section of our back yard. I couldn't be more pleased with his work. He even discounted his original estimate because we did not need top soil and I and my neighbor assisted ( if you want to call it that) some of the raking. I highly recommend Derrick and Northen Edge phil and beth"

Excavating questions, answered by experts

Trenching is a specific kind of digging. Trenching means digging a depression in the earth that’s deeper than it is wide, often with heavy machinery. Digging refers to any kind of removal of earth in order to create a human-made depression, hole, or cut in the earth’s surface. You can dig with big tools or even with just a hand shovel.

You do not have to dig footers for a deck as long as it meets local code and holds up to weather in your area. If you live somewhere that experiences high winds and earthquakes, you may need to dig for your deck posts. Deck blocks, post anchors with base plates, and helical pile systems are the three no-dig deck post options you can choose from if local code permits.

You can bury underground electrical wire six inches deep—but only if you use a rigid metal electrical conduit. For rigid, non-metallic conduits, bury the wire at least 12 inches deep. If using an underground feeder cable rated for direct burial, you'll need to place it at least 18 inches deep, as it has no conduit for extra protection.

Depending on the severity of the freeze and the method used, thawing frozen underground pipes can take anywhere from 30 minutes to several hours. Applying heat directly to the pipe using heat tape, infrared lamps, or hot water jetting can speed up the process. However, patience and careful monitoring are key to avoiding pipe damage.

How deep your septic system needs to be into the ground depends on several factors. In extremely cold environments, the tank needs to rest below the maximum frost line, which can be up to six or eight feet deep. The standard burying depth for most systems is between a few inches and four feet below ground level. Depth can also depend on the slope of the landscaping and other property variables.
